We have all been there before - you're running low on space and want to get rid of some apps. Or perhaps you just want to do your device a favor and remove old apps that you no longer use. Sure, the app is gone, but most leave behind unwanted data, taking up precious room on the /data partition, your SD card, or both. Fortunately, XDA member Dark3n has created a app to address such a situation, aptly titled SD Maid.
